Abstract

The utility model relates to a novel air filtration mask which is characterized in that a filtration cavity made of light material is a box body, one side of which is provided with a horizontal air inlet conduit. The outer end of the conduit is inserted into the position of a nose of a mask body. The top surface of the box body is provided with a telescopic vertical air inlet conduit, the length of which can be adjusted, and a water tank of a soaking sponge. A water pervious micropore of the bottom surface of the water tank is communicated with the inner of the box body. The inner of the box body is provided with an upper and a lower soaking sponge grooves which are communicated by a communicating conduit. The utility model has the advantages of simple structure, easy fabrication, small size, convenient portability and good filtration effect. The inner of the water tank can be provided with liquid with the perfume of mint for lifting spirit and refreshing brains. The novel air filtration mask is suitable for persons to use.

Description

The novel air filter face mask

The utility model belongs to mouth mask, the air filtration mouth mask that particularly a kind of nasal respiration with filter chamber is used.

At present, mouth mask commonly used is made of the multilayer gauze, is attached on the mouth and nose and breathes, breathe unobstructed inadequately, and can only the stop portions dust in air, bacterium, filter effect is good inadequately.The filter face mask that Chinese patent " ZL96209278.9 air filtration mouth mask " provides a kind of nasal respiration to use, its mouth mask cover is made up of vapour barrier, sealing adsorption layer, interior contact lining multilayer, better seal and adsorption effect are arranged, be respectively equipped with filter chamber in the both sides of mouth mask cover simultaneously, be provided with curved passage and retaining sponge in the filter chamber, with the adsorption filtration air, improve filter effect.But because curved passage is too short in the filter chamber, through using, effect is good inadequately.

The purpose of this utility model is, designs and produces a kind of novel air filter face mask, and the structure structure of improved filter chamber increases the air filtration flow process, to improve filter effect.

The technical solution of the utility model is following realization, a kind of novel air filter face mask, comprise the mouth mask body, frenulum, mouth mask body wing of nose both sides are provided with filter chamber, the filter chamber of being made by light material is box body, and box body one sidewall is provided with level to air induction conduit, and the wing of nose position of mouth mask body is inserted in the conduit outer end; The box body end face be provided with scalable adjusting length vertically to air induction conduit, be provided with tank around the conduit, built-in immersion sponge, the box body end face of tank bottom surface is provided with permeable micropore, posts the immersion spongy layer under the box body end face; The built-in upper and lower interlayer of box body, be provided with immersion sponge groove in the last interlayer, on connect vertically to air induction conduit, the circulation of air gap is left in immersion sponge groove upper edge, immersion sponge groove side is provided with UNICOM's vertical duct, with following interlayer UNICOM, is provided with the sponge groove that soaks in the following interlayer, on connect UNICOM's vertical duct, the circulation of air gap is left in immersion sponge groove upper edge.

Using method of the present utility model is, utilizes frenulum that the novel air filter face mask is worn over nose and mouth, can immerse the air disinfection thimerosal in the sponge of filter chamber, vertically immerses the air disinfection thimerosal in the tank around air induction conduit.At respiratory, the scalable adjusting length that outside air is provided with by the box body end face vertically in air induction conduit enters box body, after by upper and lower two immersion sponge grooves, dust in air is adsorbed on the cavernous body, be purified, level from the box side wall can suck the air of cleaning to air induction conduit inlet port cover body inside again.

The utility model has the advantages that, simple in structure, be easy to make; Volume is gently little, is easy to carry.Filter effect is good, can more can produce refreshing effect to the mind at the built-in mint flavored liquid of tank.Be applicable to human air filtration mouth mask.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the organigram of novel air filter face mask of the present utility model

Fig. 2 is the side view of Fig. 1

Fig. 3 is the organigram of the filter chamber of novel air filter face mask

By Fig. 1,2 as seen, a kind of novel air filter face mask comprises mouth mask body 1, frenulum 2, and mouth mask body wing of nose both sides are provided with filter chamber 3.

As seen from Figure 3, the filter chamber of being made by light material is box body, and box body one sidewall is provided with level to air induction conduit 4, and the wing of nose position of mouth mask body is inserted in the conduit outer end; The box body end face be provided with scalable adjusting length vertically to air induction conduit 5, be provided with tank 6 around the conduit, built-in immersion sponge, the box body end face of tank bottom surface is provided with permeable micropore, posts the spongy layer 7 that soaks under the box body end face; The built-in upper and lower interlayer of box body, be provided with immersion sponge groove 8 in the last interlayer, on connect vertically to air induction conduit 5, the circulation of air gap is left in immersion sponge groove upper edge, immersion sponge groove side is provided with UNICOM's vertical duct 9, with following interlayer UNICOM, is provided with the sponge groove 10 that soaks in the following interlayer, on connect UNICOM's vertical duct 9, the circulation of air gap is left in immersion sponge groove upper edge.
